What is this deficiency I was thinking it was maybe N, but wanted to ask here. And if it was N what should I do? Just feed them, as far as I know there is Nitrogen in nutrients (i am giving them everything from nutrient schedule biobizz)
The lower leaves naturally die off after a while. Not much you can do. The plant will still want grow nutrients for the first week or two of flower depending upon strain. It’s the time it really stretches to separate the buds so they get good airflow. The tops of the plant look beautiful so I wouldn’t worry about it to much. Happy Growing!!!
